My father in law has an '04 Explorer with the 4.0. He tells me he was coming home from an errand and it stopped dead, like the fuel shut off. I checked the inertia switch and it was ok. He replaced the fuel pump but that didnt fix it either. His description is as follows: when he turns the key, it will start, run about 2 seconds, if that, and shut off. It will not restart, if you want to call it that, unless it sits for a 1/2 hour or so. Then it's the same thing all over again.
Any help would be appreciated.
